They don't know how to get across, but they decide to go to God for help. The first blonde says "please God, make me twice as smart as I am so I can get across this river" God hears this and decides to help, so God turns her into a brunette and she swims across the river. The second blonde then says "please God make me ten times as smart so I can get across the river." God hears this and he turns her into a red head and she finds a boat on the river bank and goes across the river. The third one says "God, please make me one hundred times as smart so I can cross the river." So God turns her into a man and he uses the bridge.
